There's a real launcher now

The launcher is a real Electron app, not a placeholder — it docks the actual running game window inside its own frame (frameless, custom title bar), signs in with the same account as this site through a real auth-token handoff, and updates itself, with tiered forced updates for anything critical.

The hardest bug in it so far: the whole game process would just vanish — no crash, no error, nothing. Turned out to be hardware acceleration fighting the window docking. Disabling it, and adding real crash logging so the next one wouldn't take as long to track down, fixed it for good.

It's at v0.10.0 as of this post — each release a real fix or feature, not a version bump for its own sake.
